When I was little (many years ago), I received a used fashion design kit. Essentially it was a light board (small lightbulb) at an angle good for drawing. It came with pages & pages of different clothing items & they could be mixed & matched via tracing to create different designs. The pages must have been thicker, I don't remember them wearing out, but I do remember hours of fun playing with collars, sleeves, shoes, hats, etc., to get the look "just right." (BTW, I have tried to find what it was called or a picture of this toy online, but NSL.)
Anyway, this brings me to my current project, which is one of the corduroy dresses for fall/winter. And for the first one I just put on a regular collar, which I had to design myself because I bought the wrong pattern (see the 7051/7501 tale here). Here's the collar I put on the first corduroy dress.
But then I decided I wanted the collar that is on this 1960s dress pattern my mom sent.
And I remembered my mix & match fashion fun childhood & decided to change the collar myself. In this next photo you'll see (barely) the blue paper that was used for the original collar I drafted, and on top of that the curved collar in the above photo pinned & modified so it will fit the neckline but retain the curviness.
